Once you have received the .exe installation file, follow these steps to ensure a smooth setup:
Select Components: During installation, select all recommended components except for the last option (unless specifically needed).
Python Integration: A critical step is the Python component installation. Ensure you select the option to "disable the path length limit" when prompted; this only appears once and prevents errors with long file paths later on.
Directory: It is recommended to use the default installation directory provided by the installer. 4. Alternative Access (University Labs)
Many universities provide full-version access through local or virtual labs:
On-Campus: Check engineering labs (e.g., Coover rooms at Iowa State) where PSS®E is pre-installed on workstations.
Virtual Desktop (VDI): Some institutions allow off-campus students to log into a Virtual Desktop (e.g., VMware Horizon) to use the software remotely.
Note on Commercial Trials: Siemens also offers a professional PSS®E trial for organizations, but this is explicitly not available to individuals or students. PSS E Xplore Trial for Academic Users - Siemens To download and use PSS®E (Power System Simulator
